Please see the Releases page for information about the new features in LIS 7.1 and the Source page for information about the procedures to obtain a software release.
Accompanying the LIS 7.1 software is the 7.1 public release of LDT. Please see the LDT page for more information.
Accompanying the LIS 7.1 software is the 7.1 public release of LVT. Please see the LVT page for more information.
Accompanying the LIS 7.0 software is the Land Data Toolkit (LDT), designed to process data inputs for different surface models.  Please see the LDT page for more information about this new data input/parameter processing tool.
On 23 July 2014, LIS 7.0 became available for release to US government agencies and to entities working under a US government contract or grant.

Please see the Releases page for information about the new features in LIS 6.2 and the Source page for information about the procedures to obtain a software release.
On 27 Nov 2012, the LIS core team will be offering the first LIS data assimilation tutorial.  In late 2012, the official open-source release of the Land Verification Toolkit (LVT) will be available for download, along with documentation and tutorial information.
On 1 May 2011, LIS 6.1 became available for release to US government agencies and to entities working under a US government contract or grant. Please see the Releases page for information about the new features in LIS 6.1 and the Source page for information about the procedures to obtain a software release.
On 1 June 2010, the Air Force Weather Agency (AFWA) implemented LIS in its final operational configuration (FOC) as their hydro-meteorological analysis system, replacing the Agricultural Meteorology (AGRMET) model. The scheduled date to discontinue AGRMET altogether is 31 October 2010.
On 1 April 2010, LIS 6.0 became available for release to US government agencies and to entities working under a US government contract or grant. Please see the Releases page for information about the new features in LIS 6.0 and the Source page for information about the procedures to obtain a software release.
On 24 February 2009, the Air Force Weather Agency (AFWA) implemented LIS in an initial operational configuration (IOC) as the next-generation hydro-meteorological analysis system targeted to replace the Agricultural Meteorology (AGRMET) model. The LIS system produces products on a 1/4 degree spatial resolution, globally, which increases the existing AGRMET's resolution from 1/2 degree.
LIS is being used by the science definition team of the SMAP Mission (Soil Moisture Active Passive Mission) to generate 1km land surface background conditions for Observing System Simulation Experiments (OSSEs) as part of SMAP algorithm development.
LIS Wins NASA's 2005 Software of the Year Award! See the press release.
